<P><B>Syntax:</B>
</P>
<PRE>orient dim i j k 
</PRE>
<UL><LI>dim = <I>x</I> or <I>y</I> or <I>z</I>
<LI>i,j,k = orientation of lattice that is along box direction dim

<PRE>orient x 1 1 0

</PRE>
<P><B>Description:</B>
</P>
<P>Specify the orientation of a cubic lattice along simulation box
directions <I>x</I> or <I>y</I> or <I>z</I>.  These 3 basis vectors are used when the
<A HREF = "create_atoms.html">create_atoms</A> command generates a lattice of atoms.
</P>
<P>The 3 basis vectors B1, B2, B3 must be mutually orthogonal and form a
right-handed system such that B1 cross B2 is in the direction of B3.
</P>
<P>The basis vectors should be specified in an irreducible form (smallest
possible integers), though LAMMPS does not check for this.
</P>
